Butoxyethanol Ester of 2,4-D for Control of Eurasian Water Milfoil.

摘要

The development of a program for herbicidal control of water milfoil is a complex problem requiring local, State, and Federal cooperation. The first phase of the program, which consists of defining a suitable herbicide, i.e., 2,4-dichlorophenoxyacetic acid (2,4-D), and a method of application, has been completed. The second phase, which is the development of toxicological and residue data, has also been accomplished. The third phase, which consists of developing a suitable label and program of application, is the major objective of this report. Representatives from Federal, State, and private agencies met at Fort Belvoir, Virginia, 29-30 October 1974, to evaluate the program. The letter of authority, agenda of the meeting, list of attendees, and summary of aquatic plant control research program are given in Appendix A. The proposed registration label, areas of intended use, and information on the nomenclature, physical and chemical properties, use, and behavior of the herbicide are given in Appendix B. The environmental impact statement based on the U. S. Army Corps of Engineers operation in Currituck Sound and Kitty Hawk Bay, North Carolina, is presented in Appendix C. Monitoring studies by TVA, EPA, and USDI are given in Appendixes D. E. and F, respectively. A community metabolism study by East Carolina University, Greenville, North Carolina, is given in Appendix G.
